[0047] According to one embodiment of the present application, a regulating assembly is provided. As Figures 1 to 2As shown, the control assembly comprises a housing 1, a sealing layer 95 and an actuator 81. The housing 1 comprises a first shell 11, which is provided with a visible part 13 extending inwardly and provided with a protective part 93, and the inside of the protective part 93 is adapted to be provided with a pointer 92. The sealing layer 95 is arranged on the first shell 11 and forms a first sealed cavity with the inner wall of the first shell 11, which is adapted to be provided with a sealed component, and the protective part 93 penetrates the sealing layer 95. The actuator 81 is arranged in the housing 1, and the output end of the actuator 81 is respectively connected to the pointer 92 and a functional component.

[0048] In this example, the control assembly comprises a housing 1 and a sealing layer 95, the housing 1 comprises a first shell 11, and the sealing layer 95 is arranged in the first shell 11 and forms a first sealed cavity with the inner wall of the first shell 11. By arranging the first sealed cavity in the housing 1 and arranging the sealed component in the first sealed cavity, the water in the housing 1 can be prevented from damaging the sealed component. The first shell 11 is further provided with a visible part 13 extending inwardly and provided with a protective part 93, the protective part 93 penetrates the sealing layer 95, and the protective part 93 is provided with a pointer 92. The output end of the actuator 81 is respectively connected to the pointer 92 and a functional component, and the operator can observe the rotation angle of the pointer 92 from the visible part 13 to determine the rotation angle of the functional component driven by the actuator 81.

[0049] For example, the sealed component can be a circuit board 94 or the like, and the circuit board 94 is electrically connected to the actuator 81 and can be used to control the operation of the actuator 81. By arranging the circuit board 94 in the first sealed cavity, the water in the housing 1 can be prevented from damaging the electronic components on the circuit board 94.

[0050] In this example, the visible part 13 can be a visible window arranged on the first shell 11, and the visible window can be transparent plastic or transparent glass or the like.

[0051] The inner wall of the visible part 13 is provided with a protective part 93, the protective part 93 penetrates the sealing layer 95, and the sealing layer 95 and the protective part 93 are sealed to prevent water in the housing 1 from entering the first sealed cavity.

[0052] In this example, the actuator 81 can be a rotary motor, and the output shaft 82 of the rotary motor is respectively connected to the pointer 92 and the functional component at both ends. The rotation of the output shaft 82 can drive the pointer 92 and the functional component to rotate simultaneously. The operator can observe the rotation angle of the pointer 92 from the visible part 13 to determine the rotation angle of the functional component driven by the actuator 81.

[0053] For example, the functional part can be a valve body 2, the valve body 2 comprising a valve core, and the output shaft 82 of the rotary motor can be drivingly connected to the valve core. The output shaft 82 can drive the valve core to rotate to regulate the opening degree of the valve body 2. The operator can observe the rotating angle of the pointer 92 from the visual part 13 to determine the rotating angle of the valve core driven by the actuator 81, and thus determine the opening degree of the valve body 2. For example, the visual part 13 is further provided with a scale line, and the rotating angle of the pointer 92 can be determined more intuitively by the scale line pointed by the pointer 92, so that the opening degree of the valve body 2 can be determined conveniently.

[0054] In this example, the output shaft 82 can be provided with a gear, and the output end of the rotary motor can be engaged with the gear on the output shaft 82 through a gear transmission set, so as to drive the output shaft 82 to rotate.

[0055] In this example, the regulating assembly further comprises a transmission rod 91, one end of the transmission rod 91 being connected to the output shaft 82, and the other end of the transmission rod 91 being connected to the pointer 92.

[0056] In one example, the side of the pointer 92 facing the visual part 13 is provided with a light-emitting layer, and the light-emitting layer emits light when irradiated by invisible light.

[0057] In this example, the side of the pointer 92 facing the visual part 13 is provided with an invisible light-emitting layer, i.e., the light-emitting layer emits light when irradiated by invisible light. The pointer 92 emits light after being irradiated by invisible light to read the reading of the pointer 92. In this way, the reading of the pointer 92 can be prevented from being snooped by non-staff, and the flow data of the valve during operation can be prevented from being leaked.

[0058] In this example, the light-emitting layer comprises an ultraviolet light-emitting layer. That is, the pointer 92 can emit light under the irradiation of ultraviolet light. Alternatively, the invisible light-emitting layer can also be an infrared light-emitting layer, and the infrared light-emitting layer emits light when irradiated by infrared light. Of course, the light-emitting layer can also be other invisible light-emitting layers, which can be determined by those skilled in the art according to actual conditions, and are not specifically limited herein.

[0059] As shown in FIG. 1, Figure 2 In this example, the axial direction of the output shaft 82 can be defined as the X direction, and the radial direction of the output shaft 82 can be defined as the Y direction. The axial direction of the output shaft 82 is the X direction, and the radial direction of the output shaft 82 is the Y direction.

[0060] In this example, the sealing layer 95 comprises a glue layer. The material of the glue layer can be resin, sealant, etc. Of course, the material of the glue layer can be determined by those skilled in the art according to actual conditions, and is not specifically limited herein.

[0061] In one example, the part to be sealed comprises a circuit board 94, and an insulating layer is arranged between the circuit board 94 and the sealing layer 95.

[0062] The circuit board 94 is installed in the first sealed cavity. When the circuit board 94 has electronic components at one end facing the sealing layer 95, an insulating layer is arranged between the circuit board 94 and the sealing layer 95, which can avoid the influence of the sealing layer 95 on the electronic components on the circuit board 94. The insulating layer can be made of rubber or plastic with insulating properties or other insulating materials.

[0063] Of course, if the circuit board 94 does not have electronic components at one end facing the sealing layer 95, the sealing layer 95 will not affect the performance of the circuit board 94, and the insulating layer can not be provided. The sealing layer 95 can be in contact with the circuit board 94.

[0064] In one example, as shown in Figure 1 and Figure 2 The control assembly further comprises a second housing 12, the open end of the second housing 12 is sealingly connected to the open end of the first housing 11, and the actuator 81 is installed in the second housing 12.

[0065] As shown in Figure 1 and Figure 2 The control assembly further comprises a second housing 12, the open end of the second housing 12 is sealingly connected to the open end of the first housing 11. The actuator 81 is installed in the second housing 12. The inner wall of the second housing 12 is provided with a first protruding portion 121 protruding inwardly, and the actuator 81 is fixedly installed on the first protruding portion 121. The first protruding portion 121 is provided with a first through hole, and the output shaft 82 is arranged in the first through hole to be connected to the valve core. Alternatively, one end of the valve rod 22 is arranged in the first through hole to be connected to the output shaft 82, and the other end is connected to the valve core.

[0066] In one example, a second sealing member 96 is arranged between the first housing 11 and the second housing 12.

[0067] The second sealing member 96 is arranged between the open end of the first housing 11 and the open end of the second housing 12. That is, the two opposite sides of the second sealing member 96 abut against the first housing 11 and the second housing 12 respectively, so as to improve the sealing performance of the housing 1.

[0068] The second sealing member 96 can be a sealing ring made of rubber or silicone, which can be determined by those skilled in the art according to the actual situation, and is not limited here.

[0069] In one example, the second housing 12 is provided with a connecting portion in the circumferential direction, and the connecting portion is adapted to connect the first housing 11. The second sealing member 96 is provided with a avoiding portion to avoid the connecting portion.

[0070] The second shell 12 is provided with a connecting portion in the circumferential direction, and the second shell 12 is fixedly connected to the first shell 11 through the connecting portion. For example, the second shell 12 is provided with a threaded hole at the opening end, that is, the connecting portion, and a fastener such as a bolt is passed through the first shell 11 and screwed with the threaded hole to fix the first shell 11 to the second shell 12. The second seal 96 is provided with a relief portion to avoid the threaded hole, so that the fastener can be smoothly screwed into the threaded hole. Moreover, by providing the relief portion on the second seal 96, the relief portion can not only avoid the threaded hole, but also make the second seal 96 an integral molding structure, thereby facilitating installation.

[0071] In one example, as shown in Figure 7 The relief portion is a circular arc segment 962, and the second seal 96 is provided with a plurality of the circular arc segments 962 in the circumferential direction. Two adjacent circular arc segments 962 are connected by a connecting segment 961, and the two sides of the connecting segment 961 abut against the first shell 11 and the second shell 12, respectively.

[0072] As shown in Figure 7 The relief portion on the second seal 96 can be a circular arc segment 962, which can avoid the connecting portion, for example, the threaded hole. The circular arc segment 962 protrudes inward and can be hidden in the inner cavity of the shell 1, thereby improving the overall aesthetics of the shell 1.

[0073] In this example, the second seal 96 is provided with a plurality of circular arc segments 962 at intervals. The number of circular arc segments 962 corresponds to the number and position of the connecting portions on the second shell 12. For example, the circular arc segments 962 can be five, six, or seven, etc. The number of circular arc segments 962 can be determined by a person skilled in the art according to actual conditions, which is not limited specifically herein. Two adjacent circular arc segments 962 are connected by a connecting segment 961, so that the second seal 96 is an integral molding structure, thereby facilitating installation.

[0074] In one example, as shown in Figure 2 The control assembly further includes a power supply assembly 98, which is detachably installed on the outer wall of the shell 1 and electrically connected to the actuator 81 and the circuit board 94 to provide power for the actuator 81 and the circuit board 94. The power supply assembly 98 is externally connected to the shell 1, thereby facilitating replacement and maintenance, etc.

[0075] As shown in Figure 2 In this example, the power supply assembly 98 includes a power supply shell and a power supply cover 99, and a battery is installed in the power supply shell. The power supply cover 99 is sealingly provided at the opening end of the power supply shell. A third seal 97 is provided between the opening end of the power supply shell and the power supply cover 99, thereby playing a role in preventing water and moisture.

[0076] In this example, reinforcing ribs can be arranged on the inner wall of the power supply shell to improve the strength of the power supply shell and prevent damage to the power supply shell during welding. The reinforcing ribs can be arranged in multiple rows and spaced apart on the inner wall of the power supply shell to further improve the strength of the power supply shell.

[0077] In this example, the power supply shell can be fixedly connected to the shell 1 by screws or bolts and the like. The outer wall of the power supply shell is provided with a connecting plate, and the connecting plate is provided with a third connecting hole. The fastener is inserted into the third connecting hole and screwed to the shell 1, thereby fixing the power supply shell to the shell 1. The connecting plate can be provided with multiple connecting plates, for example, the connecting plates can be symmetrically arranged on both sides of the power supply shell, or three or four connecting plates can be arranged, etc. The skilled person can determine the number of connecting plates according to the actual situation, which is not limited here.

[0078] According to another aspect of the present application, a valve device is provided. The valve device comprises a valve body 2 and the control assembly of the above-mentioned embodiments, and the control assembly is connected to the valve body 2.

[0079] In this example, the valve device further comprises a first connecting member 6, a second connecting member 4, and a first limiting member 3. One end of the first connecting member 6 is connected to the shell 1, and the first connecting member 6 is provided with a clamping portion. One end of the second connecting member 4 is connected to the valve seat 21, and the second connecting member 4 is clamped to the clamping portion. One end of the first limiting member 3 is radially inserted into the side wall of the first connecting member 6 and the second connecting member 4. One end of the valve stem 22 is axially inserted into the first connecting member 6 to be connected to the actuator 81, and the other end is axially inserted into the second connecting member 4 to be connected to the valve core.

[0080] The first connecting member 6 can be integrally formed with the shell 1, thereby improving the stability of the connection between the first connecting member 6 and the shell 1, and the integral forming process is simple, which can also reduce the assembly steps of the valve device. The second connecting member 4 can be fixedly connected to the valve seat 21 by screws or bolts and the like, or can be integrally formed with the valve seat 21.

[0081] In this example, the valve body 2 comprises a valve seat 21, a valve core, and a valve stem 22. The valve seat 21 has a passage, and the valve core is arranged in the valve seat 21 to control the opening or closing of the passage. The valve seat 21 is connected to the second connecting member 4, and the outer wall of the shell 1 is connected to the first connecting member 6, which can be clamped to the second connecting member 4. As shown in Figure 4 The second connecting member 4 is provided with a second through hole 46 along the axial direction to avoid the valve stem 22. The first connecting member 6 is hollow to allow one end of the valve stem 22 to pass through the first connecting member 6 to be connected to the valve core, and the other end of the valve stem 22 to pass through the second connecting member 4 and the shell 1 to be connected to the output shaft 82 of the actuator 81. The output shaft 82 can adjust the opening degree of the valve core through the valve stem 22.

[0082] The first connecting piece 6 is in a whole circular ring structure, and the inner wall of the first connecting piece 6 is provided with a clamping part. The second connecting piece 4 is in a whole circular ring structure, and the first connecting piece 6 can be sleeved on the outer periphery of the second connecting piece 4 and clamped on the radial side wall of the second connecting piece 4. The first limiting piece 3 can be first threaded on the side wall of the first connecting piece 6, then threaded on the second connecting piece 4, and finally connected to the inner wall of the first connecting piece 6 to fix the limiting piece. Thus, the first connecting piece 6 and the second connecting piece 4 can be doubly fixed.

[0083] The first connecting piece 6 is in a whole circular ring structure, and the inner wall of the first connecting piece 6 is provided with a clamping part. The second connecting piece 4 is in a whole circular ring structure, and the first connecting piece 6 can be sleeved on the outer periphery of the second connecting piece 4 and clamped on the radial side wall of the second connecting piece 4. The first limiting piece 3 can be first threaded on the side wall of the first connecting piece 6, then threaded on the second connecting piece 4, and finally connected to the inner wall of the first connecting piece 6 to fix the limiting piece. Thus, the first connecting piece 6 and the second connecting piece 4 can be doubly fixed.

[0084] In this example, the first connecting piece 6 can be provided with a plurality of clamping parts, and the second connecting piece 4 is correspondingly provided with a plurality of matching parts, and each clamping part is correspondingly clamped on the first matching part. By providing a plurality of clamping parts, the stability of the connection is improved. For example, two, three or four or the like can be provided, and the person skilled in the art can determine according to the actual situation, which is not specifically limited herein.

[0085] In one example, as shown in Figure 4 and Figure 5 The clamping part includes a clamping groove 61 provided on the inner wall of the first connecting piece 6, and the outer wall of the second connecting piece 4 is provided with a clamping block 41, which can be clamped in the clamping groove 61.

[0086] As shown in Figure 4 and Figure 5 In this example, the inner wall of the first connecting piece 6 is provided with a clamping groove 61, and the radial outer wall of the second connecting piece 4 is provided with a clamping block 41. When the second connecting piece 4 is embedded in the first connecting piece 6, the clamping block 41 can be clamped in the clamping groove 61.

[0087] As shown in Figure 5 In this example, the clamping groove 61 can be provided with a plurality of clamping grooves 61, which are spaced apart on the inner wall of the first connecting piece 6, and the outer wall of the second connecting piece 4 is correspondingly provided with a plurality of clamping blocks 41. By providing a plurality of clamping grooves 61, the stability between the first connecting piece 6 and the second connecting piece 4 can be improved.

[0088] For example, two card slots 61 can be provided, which are symmetrically arranged on both sides of the first connecting member 6. Alternatively, three or four or more card slots 61 can be provided, which are evenly spaced on the inner wall of the first connecting member 6. Of course, the number and arrangement of the card slots 61 can be determined by the actual situation, and are not specifically limited herein.

[0089] In one example, as shown in Figure 5 The stop block 614 is arranged in the card slot 61 and is adapted to limit the axial movement of the clamping block 41 along the first connecting member 6.

[0090] As shown in Figure 5 In this example, the stop block 614 is arranged in the card slot 61, and when the clamping block 41 is clamped in the card slot 61, the stop block 614 can limit the axial movement of the clamping block 41.

[0091] That is, the first connecting member 6 is provided with an opening at one end away from the housing 1, and the card slot 61 is communicated with the opening. The clamping block 41 can enter the card slot 61 from the opening. The first slot wall 611 and the third slot wall 613 opposite to each other in the circumferential direction of the card slot 61 can limit the rotation of the clamping block 41 along the circumferential direction of the first connecting member 6. The card slot 61 also has a second slot wall 612 opposite to the opening, and the stop block 614 is arranged opposite to the second slot wall 612, and the stop block 614 and the second slot wall 612 have a first gap therebetween, and the clamping block 41 can be clamped in the first gap, and the two ends of the clamping block 41 in the axial direction can abut against the stop block 614 and the second slot wall 612, respectively, to limit the axial movement of the clamping block 41.

[0092] In this example, the stop block 614 is also provided with a bypass opening, and the clamping block 41 can pass through the bypass opening and be clamped into the first gap. During installation, the clamping block 41 first passes through the bypass opening and then rotates in the circumferential direction, so as to be clamped in the first gap.

[0093] In this example, the stop block 614 can be connected to the first slot wall 611, and the stop block 614 and the third slot wall 613 have a second gap therebetween, which constitutes the bypass opening. Alternatively, the two ends of the stop block 614 are connected to the first slot wall 611 and the third slot wall 613, respectively, and the stop block 614 is provided with a bypass opening at the middle position, so that after the clamping block 41 passes through the bypass opening, it can rotate in two directions in the circumferential direction, and can be clamped in the first gap, thereby improving the convenience of installation of the second connecting member 4.
